Terrestial herbs and aquatic herbs are of natural origin with significant medicinal properties. These properties were selected and aimed to provide antimicrobial and anti-odour activities after finishing with nine different fabric samples in the present study. Hemigraphis colorata and Bacopa monnieri are the two herbs selected and a novel herbal composite (HC1) was developed. Composite was finished onto fabric samples using Pad-dry cure process. Finished fabrics were subjected to antibacterial activity using standard EN ISO 20,645 test method against Escherichia coli and Staphylococcus aureus. To prevent odour from physical activities, aromatic oil was finished onto fabric samples; followed by testing anti-odour activity using Swiss standard SNV 195,651. Test results of antibacterial activity of herbal composite (HC1) finished fabrics revealed good inhibitory action against both test bacteria. Aromatic efficiency of herbal composite finished fabrics showed significant aromatic efficiency. Statistical evaluation determined that there was no significant difference (p–1) between finished and control fabrics in terms of antibacterial activity and aroma. Results for the biocompatibility of the herbal composite finished fabrics revealed that the composite concentrations did not inhibit the growth of fibroblast cells; thus indicating the biocompatibility of the herbal composite finished fabric samples. The present study would be considered highly significant by providing an eco-friendly and sustainable products for developing medical textile products and smart home textile products.
陆地草本植物和水生草本植物是天然的，具有重要的药用价值。在本研究中，我们选择了这些特性，目的是在九种不同的织物样品整理后提供抗菌和抗臭活性。以半金莲和假马尾草为研究材料，开发了一种新型复方药材HC1。采用垫干固化工艺在织物样品上制备复合材料。用标准EN ISO 20,645对大肠杆菌和金黄色葡萄球菌进行抗菌活性测试。为了防止身体活动产生的气味，在织物样品上涂上芳香油;然后使用瑞士标准SNV 195,651测试抗气味活性。草药复合材料(HC1)整理织物的抑菌活性测试结果表明，其对两种试验菌均有良好的抑制作用。草本复合整理织物的芳香效率显著。统计评估表明，在抗菌活性和香气方面，成品织物和对照织物之间没有显著差异(p-1)。结果表明，中药复合整理织物的生物相容性对成纤维细胞的生长没有抑制作用;从而表明草药复合整理织物样品的生物相容性。本研究为医用纺织品和智能家用纺织品的开发提供了一种环保、可持续的产品，具有重要意义。

Polyacrylonitrile (PAN) carbon fibers are often used to prepare high-performance paper-based materials owing to their high strength, good electrical and thermal conductivity, and superior comprehensive properties. In this study, a novel method for preparing PAN-based carbon fibers by centrifugal spinning was developed, and a stable and homogeneous PAN carbon fiber paper was successfully obtained. Subsequently, the formation process, microscopic morphology, electrical conductivity, electrochemical performance and hydrophobicity of the PAN carbon fiber paper were studied and evaluated. The results showed that the electrical conductivity of the PAN carbon fiber paper prepared via this method reached 43.250 s·cm−1, resistivity was as low as 0.023–0.033 Ω·cm, and contact angle exceeded 140°. This study adopted a new method to prepare PAN carbon fiber paper, which provided another method for the preparation of high-performance fiber paper.

Air pollution has become a significant global environmental issue, leading to adverse health effects and respiratory diseases. To address this challenge, expanded polytetrafluoroethylene (ePTFE) membrane-based fibrous filters have gained popularity in the past decade. However, the thinness and low mechanical strength of ePTFE membranes make them susceptible to damage from particle collisions. As an alternative to ePTFE membranes, PTFE emulsion has emerged as a promising approach to enhance filtration efficiency. However, due to PTFE's low surface energy and high crystallinity, it is difficult for PTFE to self-bond into a membranes and adhere to substrates. Therefore, the filtration efficiency of PTFE-impregnated filter materials does not meet the requirements for ultra-low emissions, and they have poor wear resistance, resulting in a short service life. Herein, we fabricate a PTFE emulsion foam-coating membrane filter. The influences of the contents of PVA on the film morphology, air permeability, pore size and distribution, abrasive resistance and antistatic properties were analyzed. The self-cleaning performance was simulated and the filtration performance was measured as well. Notably, the frictional mass loss index of the PTFE emulsion foam-coating membrane filter was 0.07. After 30 cycles, the filtration efficiency was 98.93%, and the strip ratio was 91.03%. Our design of the PTFE emulsion foam-coating provided a new direction for the application of PTFE emulsion in the filtration field with superior self-cleaning, antistatic and high filtration efficiency performances.

In this study, the authors proposed a method to fabricate a resistive stretch textile sensor from polyester spandex (PET/SP) fabric and commercial single-walled carbon nanotube (SWCNT). In addition, we designed and trained a one-dimension convolutional neural network to classify four resistance workouts, which employed data acquired from the proposed sensor as the input. To figure out the most appropriate PET/SP sample for the deep learning application, we investigated morphologies and characterization of three samples in distinct conditions of the coating process. Data acquired from the proposed sensor illustrated the significant difference between activated and non-activated muscle groups in each specific exercise. With the PET/SP sample which met the requirements of the application, after 100 epochs, the deep learning model achieved 97.2% training accuracy and 90% test accuracy. This study demonstrates that the SWCNT-coated PET/SP stretch textile sensor can be utilized effectively to track the activity of forearm muscles during resistance training. Other than that, the proposed 1D-CNN, with the advantage of training time and computational cost, is able to classify time series data with high performance and thus can be applied widely in various deep learning applications, especially in the healthcare and sports industries.

This study aims to develop composite laminates for the manufacture of prosthesis socket with enhanced mechanical performance. Layered hybridisation of fabrics (i.e. glass, carbon, and Kevlar fabrics) is used to manufacture hybrid composite laminates by resin infusion via vacuum bagging method. The response of these materials to compression loading is investigated by using compression-loading testes and the load-bearing ability was examined by tensile strength tests. Moreover, finite element analysis has been carried out by using the Abaqus software to predict the compressive failure load and damage failure modes for all sockets samples. Experimental results revealed that the hybrid laminates exhibited more stability and higher absorbing energy compared to non-hybrid laminates during compressive loading tests. Furthermore, the hybridisation of fabrics layers can play key role for improving the tensile strength properties of hybrid composite laminates compared to composite laminates without hybridisation. The numerical simulation results of compressive failure load and damage failure modes are in accordance with experimental results qualitatively as well as quantitatively.

Antibiotics released in the water pose a serious threat to human and ecological health. Therefore, it is of great importance to effectively remove antibiotics from wastewater. In this study, recyclable bacterial cellulose/sodium alginate/zeolitic imidazolate framework-8 (BC/SA/ZIF-8) aerogel composites were prepared by chemical cross-linking and in situ growth in freeze-drying. The successful preparation of the composite aerogel was confirmed by scanning electron microscope (SEM), Fourier Transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) analysis. The results reveal that BC/SA/ZIF-8 aerogel composite has significantly high BET specific surface area of 165.24 m 2 /g than that of BC/SA at 7.39 m 2 /g. The BC/SA/ZIF-8 composite aerogel exhibited excellent adsorption performance for tetracycline hydrochloride, with a maximum adsorption capacity of 746.27 mg/g. The adsorption process followed the pseudo-second-order kinetic model and Langmuir adsorption isotherm model. Moreover, the reusability test on BC/SA/ZIF-8 composite aerogel revealed an insignificant decline in adsorption after six cycles. Therefore, BC/SA/ZIF-8 composite aerogel has a high potential as a novel and recyclable adsorbent for efficient removal of tetracycline hydrochloride from water.

Polyethylene terephthalate (PET) polyester fabric has been treated with different concentrations of sodium lignin sulphonate (SLS), a lignin based sustainable flame retarding agent. Treated PET fabric has exhibited different chemical loading on its surface varying from 15 to 60% depending on the concentration used. Treated fabric has shown 40–70% more limiting oxygen index (LOI) value as compared to the control PET fabric. 200 g/L SLS treated PET fabric (with 35% chemical loading) has shown LOI value of 27. In addition to it, melt dripping property of all the treated PET fabrics have been found to be stopped with lower shrinkage during combustion, as observed from the UL94 test results. TG analysis of the said fabric has shown 20–25% more char mass retention and lower rate of weight loss as compared to the control one. Char morphology of the control and the treated fabric has also been examined in different magnifications and analyzed in detail. Forced combustion test of the sodium ligno-sulphonate treated PET fabric has revealed 82% lower peak heat release rate (PHRR) as compared to the control PET fabric with less amount of carbon monoxide liberation during burning. Besides, a possible mechanism lies behind the flame retardancy of the SLS treated PET fabric also has been expressed and discussed scientifically.

In this study, a novel multifunctional carpet test device was proposed to overcome deficiencies of current technology, including manual operation error and fixed load. The newly developed test device can automatically perform short-term static loading, long-term static loading and thickness measurement on five samples, simultaneously. The application of the load is achieved by using pneumatic system elements and automation of the developed test device is obtained by a PLC (Programmable Logic Controller) software. The device was verified according to “trueness” and “precision” criteria via statistical analyses. As a result of trueness determination, the Mean Absolute Percentage Error (MAPE) values of the developed test device were between 0.001–0.023, in comparison to that of the traditional carpet thickness tester, which exhibits very close trend between two measurements. The precision analysis results revealed no significant difference in 95% confidence interval between developed test device and the carpet thickness tester. Moreover, the developed test device is capable for thickness loss test by brief moderate loading, prolonged heavy loading and carpet thickness measurement, following related international standards.

The urgent need for flexible strain sensors that are both aesthetic and functional is addressed, given the rapid development of smart wearable technology and the improvement of material level. To achieve this, silver-plated yarns based on nylon and nylon wrapped spandex were directly knitted into the sensor using cross-knit intarsia and plating technology. Five samples, with varying percentages of loops and tuck loops, were designed. The results indicated that the sensor demonstrated a GF of 2.80 kPa −1 at the Lx-axis and 3.67 kPa −1 at the Ly-axis, showing good repeatability during 1000 cycles of stretch/release. Moreover, it exhibited fast responsiveness, enabling it to discriminate between different rates of stretch. The sensor's potential for application in wearable smart medical monitoring was demonstrated by its ability to be embedded in garments for joint motion monitoring. These findings collectively suggest that the designed knitted strain sensor holds promising potential for use in the field of wearable smart medical monitoring.

This study deals with the prediction of the mechanical properties of wool bundle fibers and the characterization of the fracture performance of fiber fracture sound. Acoustic emission detection was used to record the fracture sound of wool fibers. According to the fracture sounds, the tensile properties of the bundle fibers were obtained. Acoustic emission provided a convenient method for obtaining fibers breaking elongation distribution. Based on the fiber bundle model and fiber breaking distribution, the fracture strength and elongation of bundle fibers could be predicted. Meanwhile, based on the correlation between the amplitude of fiber fracture sound and fiber breaking strength, the single fiber breaking strength could be predicted and the tensile properties of bundle fibers could also be obtained. The prediction results based on bundle fiber fracture sound were more similar to the measured results. Besides, the number of fibers within the bundle increased, the fiber interaction was also enhanced, and the bundle fiber strength prediction results were affected. This work was considered to have the potential of being used in the prediction of mechanical properties of natural fiber composites.
